There were no apparent injuries or marks on the body and at this moment in time, do not believe the death is suspicious.

Officers are now appealing to people who use the area for information.

Detective Sergeant John Coleman said: “The area where the man was found is extremely remote and is used by walkers, engineers and rangers for the park. What we know is he was last seen at around 4.30pm on Friday 11 December 2015 on the track near to where he was found and would appeal to anyone with information to contact us.

“We are trying to find out who he is so we can tell his family but unfortunately he did not hold any ID. When he was searched, the man had money and three train tickets. One was from Ealing train station to Euston which was bought at 9.10am on Friday 11 December 2015. The other tickets were return from Euston to Piccadilly bought at 9.50am the same day.

“At this moment in time, we do not know whether the man is local or is visiting the area. I would appeal to owners of hotels or guest houses to call us if they believe personal belongings have been left in their room and no one has come back to claim them.”
